Poznań-Warsaw team points to a plausible home system of the interstellar comet 2I/Borisov

A team of astronomers: Piotr A. Dybczyński (UAM), Małgorzata Królikowska (CBK PAN) and Rita Wysoczańska (UAM) have published recently a preprint (https://arxiv.org/abs/1909.10952) in which they propose a double star Kruger 60 as a possible home system for an interstellar comet I/Borisov discovered on August 30. The most important result supporting this hypothesis is a very small relative velocity of these two objects during their approach to each other one million years ago. The miss-distance is a bit too large, 1.7 pc, but it may be lowered when more precise data are available, especially the precise radial velocities of the components of the Kruger 60 system.
